Introducing the 12-inch TS 410 and 14-inch TS 420 STIHL Cutquik cut-off machines with the revolutionary X2 Air Filtration System. The X2 system delivers 99.96 percent clean air to the machine and not only eliminates the need to clean the filter, reducing down time due to on the job filter maintenance and costly repairs due to particulate damage, but also extends filter life. Proper filter maintenance is very easy: do not clean the filters; run the machine until there is a noticeable drop in power; then simply replace the filters. These units feature a new anti-vibration system that reduces vibration by 43 percent compared to previous models, providing maximum comfort and lessened fatigue.
